move from cmd.exe 32 bit to cmd.exe 64 bit

morning
i have windows 7 home premium 64 bit. when i execute my commande console (cmd.exe) i have an error message that talk about an incompatibility of my command with my operating system.
i thing the problem is that my consol command cmd.exe change (i don't know how and when) to 32 bit OS.
can anybody tel me what to do?

Hey Welcome to the forums!

I don't think cmd.exe is to blame. Rather, as it says, the command you're trying to execute.

What command were you trying to execute?

hi fire cat
i want to go to the concole ms-dos. i run cmd in the run option on start and it appears the error message.
